Title: Hirotaka Ueno: Innovator in Imaging Technology
Introduction
Hirotaka Ueno is a notable inventor based in Saitama, Japan. He has made significant contributions to the field of imaging technology, holding a total of 4 patents. His work focuses on enhancing the functionality and efficiency of imaging apparatuses.
Latest Patents
Ueno's latest patents include an exposure control unit and an imaging apparatus. This exposure control unit comprises a photometer, a designator, a first calculator, a first counter, a selector, a second calculator, a categorizer, and an exposure controller. The photometer features multiple photometric zones, allowing the designator to designate these zones one by one as target zones. The first calculator computes a first difference, while the first counter counts a first determination number. The selector identifies the target zone where the first determination number exceeds a second threshold. The second calculator then calculates a categorization value, enabling the categorizer to classify the target zone into low- or high-luminous zones. The exposure controller adjusts the exposure of the imaging apparatus based on the partial value of light for one of these zones.
Another significant patent is the diaphragm control apparatus for interchangeable lens cameras. This apparatus is integrated into the camera body, where a controller operates a stepping motor to move a slider away from its origin position. The controller subsequently drives the motor back toward the origin position and detects the slider's position after a specified waiting time. This process allows for the establishment of an initial excitation pattern based on the detected positions and the moving distance of the slider.
